Abstract
For determining the optimal conditions of the cutting process (material and tool geometry, process parameters), quantitative data are necessary concerning the roughness of surfaces. Using experimental research methods, this work aims at determining equations between surface roughness and parameters of the milling, process for some polyamides samples (PA66, PA66 – GF30 and PA66 MoS2). PA66, PA66 – GF30 and PA66 MoS2 polyamides are technical thermoplastics with excellent mechanical and physical properties, increasingly used in industrial machinery. Keywords: surface roughness, milling, polyamides
